I'm pretty sure; under WL 4.5.1, 5.1, and now 6.0, our 1.1 entity beans
have always been BMP + CMT! So unless WL has been breaking the specs, or
I'm doing something egregiously wrong...

Are you sure Gene? transaction demarcation and transaction isolation are
implemented jointly by jdbc + jta. I have never seen a truly CMT for BMP
beans; it was kinda like a hole in the spec; that's why both isolation level
and CMT in entities where left out from the spec. I believe, if Mark Hapner
is still around the list like he used to, that he may clarify this; If I
remember correctly, he already has; Please check the archives.
